FRED™C-Series - Centralized Dust & Smoke Collectors

How the C Series Dust Collectors Operate

Contaminated air enters the collector above the filter cartridges. Specially designed components in the cabinet uniformly distribute the contaminated air across the top of the filters.The contaminated air flows downward at a steady velocity. Dust is conveyed to the settling area below the filters by both air flow and gravity. Extremely small particulate is collected on the filter media, allowing clean air to return to the workplace or outside environment. Once particulate collection on the filters is sufficient to reduce air flow, the patented reverse jet pulse cleaning system propels the collected dust off of the filters and into the settling area.

Downflow:

The C Series downflow/verticle design produces zero velocity at the base of each filter stack, allowing the dust to settle uninhibited below the cartridges, thereby eliminating re-entrainment.

Cartridge Filters:

The standard 80/20% cellulose/polyester cartridge media is high in resin content to provide mechanical resilience, and has pleat-lock construction. Standard cartridges are rated for temperature up to 160 degrees Fahrenheit. High temperature cartridges are also available.

Dust Settling:

The C Series design allows larger dust contaminates to have a clear path to the dust settling area and finer particles to be collected by the filters.

Venturi:

Venturi reverse pulse cleaning is the quick release of pressure through a blow tube into a venturi enductor tube into a cartridge filter. A higher volume of air is induced via this principle. The resulting burst of compressed air is more equally dispersed across the filter resulting in greater cleaning effectiveness compared to typical reverse pulse cleaning.

Pulse Jets:

Pulse jet performance and economy are maximized by Optimizing the orifice size and position. Pulse jet performance and economy are maximized by Optimizing the orifice size and position.

Pulse Jets:

The motor, fan and inlet cone are packaged into a tubular centrifugal fan arrangement for greater performance, quieter operation and simplified maintenance.

Dust Collection Efficiency:

The major obstacle to dust collection efficiency is re-entrainment, the refiltering of dust that has been stirred up prior to settling. The goal is to dislodge the dust from the filter and allow it to settle in the hopper below.

The C Series utilizes patented downflow/verticle technology to minimize re-entrainment and extend filter life. Carefully managed inlet air velocity ensures that the air only flows downward, never upward or sideways. This prevents air movement below the filters where the dust has settled and results in effective cleaning while the dust collector is operating and shut down.
